I apparently got one at the same time too, but I missed it distracted by this HN thread :). Not only I got o3-mini (which I already noticed on the Limits page), but they also gave me access to o1 now! I'm Tier 3; until yesterday, o1 was still Tier 5 (IIRC).
Thanks OpenAI! Nice gift and a neat distraction from DeepSeek-R1 - which I still can't use directly, because their API stopped working moments after I topped up my credits and generated an API key, and is still down for me... :/.
